Using PN and Arwen's basically, since I like that hard core/realistic experience, but I am annoyed that I can't craft primers and specific ammo cases as well as convert explosives to gunpowder, etc.

Can anyone recommend a crafting mod that is comprehensive but isn't too overpowered, meaning, makes ammo far too easy to get?

http://www.newvegasnexus.com/downloads/file.php?id=41013 by antistar is a great ammo crafting mod and very balanced, imo. it opens up the ability to craft all types of ammo, and explosives, breakdown casings and primers so you can craft them different types, and more.

Thanks! Just what I was looking for.
